How to install the plastic steel solar mixing valve

What is a tekmar mixing valve made of?

The body of the tekmar mixing valve is constructed from cast iron which has been found to be the most economical and suitable material for the high stress environment in which the valve operates. As with all ferrous components in a hydronic system, certain precautions are required in order to prevent any appreciable corrosion from occurring.

Do I need a separate isolating valve?

each TMV will ensure this requirement is met.If the ENWARE AQUABLEND 1500 Solar Thermostatic Mixing Valve is to be installed without the supplied inlet control valves then it will be necessary to install a separate isolating valve, non-return alve and strainer to both inlets to the valve. Strainers must be fitted to prevent any par

What should be done if a mixing valve is used manually?

When the mixing valve is used manually, adequate corrosion control must be provided and the valve flap should be rotated through its full range on a regular basis in order to prevent seizure. If the valve flap does become jammed, do not force it to move as internal components may be damaged.

What is a mixing valve?

mixing valve from corrosive components. The heat exchanger is typically used to separate oxygen permeable pipe or copper pipe from Heating System ferrous components. A heat exchanger with a high rate of heat transfer (Btu per hour) is recommended to prevent the valve from oscillating.

Can a mixing valve cause galvanic corrosion?

Galvanic corrosion results when different metals are use in the same piping network. The mixing valve is commonly used in both copper and mild steel (black iron) piping systems. Mild steel pipe does not cause cast iron to corrode and is the recommended piping material for use with the mixing valve.

How to reduce the risk of dam-age to a mixing valve?

To reduce the possibility of dam-age to the valve, install a tekmar Mixing Control with an “exercis-ing function”. When the valve flap is exercised regu-larly, the full range of motion of the mixing valve remains free of corrosion. due to poor water quality and a limited range of valve flap motion.
